This invention relates to cookers, and more particularly to commercial cookers for use in processing fruit in the manufacture of candied fruit.

In the commercial processing of fruits, to produce candied fruit, the density of the syrup used must be progressively increased, and great pains must be taken to prevent the scorching of the syrup and to properly control the gradual thickening of the syrup as the process progresses.

An object of the present invention is to produce a cooker oi the type indicated lending itself to precise control and completely eliminating any possibility of scorching the syrup.

The invention consists in the novel construction, arrangement and combinations of parts hereinafter more particularly described and claimed.

One sheet of drawings accompanies this specification as part thereof in which like reference characters indicate like parts throughout.

Figure 1 is a vertical transverse section through an embodiment (largely diagrammatical) of the present invention; and,

Figure 2 is a plan view of the device illustrated in Figure 1.

Referring to the drawings, I indicates a container herein illustrated as of cylindrical crosssection but which may be of any shape desired. The container is provided with spaced bottoms 2 and 3 providing a cooling chamber at the bottom of the container and the bottoms Z and 3 are provided with aligned openings to receive a downwardly directed pipe 4, the inner mouth of which is covered as by a screen II. The downwardly directed pipe 4 is associated with suitable angle bends 5 or otherwise formed to provide a change of direction laterally of the container 1 and upwardly as through extensions 1. The vertical extension I is provided with a lateral pipe connection 8 communicating with the container I through its side wall adjacent the top but below the normal level of the syrup I2 to be used in the process.

A water container 6 is provided to surround the yertical pipe I with portions of its lateral connections to constitute a water jacket around those portions of the pipes 4, 1 and 8 positioned laterally of the container I, and a burner 9 supplied with gas or other suitable fuel through a pipe [0 is positioned below the water jacket 5. A water inlet I3 is provided communicating with the space between the bottoms 2 and 3 of the container and an outlet stop I 4 is provided to 3 Claims. 99-239) '2 permit the use of a stream of cooling medium through this space when desired.

In use, the fruit to be cooked and candied is placed in container l and the container l and pipes 4, 'l and 8 filled with syrup while the water jacket 5 is filled with Water. Heat being applied through burner 9 to the water in jacket 6 is communicated to the syrup in the vertical reaches of pipes 4, I and 8, creating an upward current of the syrup in those pipes and a corresponding downward current in the syrup within the container I.

If the circulation of the syrup becomes too sluggish as the thickening process advances, it may be augmented by applying a cooling medium between the double bottom of the container I and the regulation of the supply of heat from the burner 9 and cooling medium between the bottoms of container I provides an extremely flexible control for the circulation of the syrup at all times.

The container has no top and preferably the vertical riser pipe 1 will be left uncovered, permitting the evaporation of moisture from the syrup during the cooking process.

Various modifications in the shape and arrangement of the various parts will readily suggest themselves to those skilled in the art and to accommodate the apparatus to particular locations in which it may be used, but within the scope of the present invention as claimed.

Having thus described my invention, I claim:

1. A cooker for fruit comprising a double bottomed container adapted to receive fruit and to be filled with syrup to a predetermined level, the bottoms having aligned openings, a conduit communicating said openings and extending in a U- bend below the container and exteriorly of the container to a point above the top of the container, with a second conduit communicating the container with the first mentioned conduit below the predetermined syrup level, a water jacket surrounding parts of said conduits, means for applying heat to the water in the water jacket and means for supplying a cooling medium between the bottoms of the container.

2. A cooker for fruit and the like comprising a container adapted to receive fruit and to be filled with syrup to a predetermined level, a conduit extending from the lower part of the container exteriorly thereof to the upper part thereof and opening into the container below the predetermined syrup level, said conduit forming with the container a complete circuitous course for the syrup, means for extracting heat from the syrup between the fruit and the lowest reach of the conduit and means for supplying heat to the syrup between the lowest reach of the conduit and the top of the container.

3. A cooker for fruit and the like comprising, a double-bottomed container adapted to receive fruit and to be filled with a syrup to a predetermined level, a conduit communicating with the bottom of said container, passing through the double bottom, and extending exteriorly of the container and opening into the side wall of the container below the predetermined syrup level, forming with the container a complete, uninterrupted, circuitous course for the syrup, means for applying heat to portions of said conduit exteriorly of the container to induce a current in the syrup from the bottom to the top, and means for supplying a cooling medium between said bottoms.

JOHN S. MAGLEY.
